- Pretreatment colostomy in patients with anal squamous cell carcinoma: Risk factors for a permanent stoma(2022) SOBRADO, Lucas F.; NAHAS, Caio S. R.; MARQUES, Carlos F. S.; SOBRADO, Carlos W.; NAHAS, Sergio C.Background The current standard of care for anal squamous cell carcinoma (SCC) is concurrent chemoradiation (CRT), which enables tumor eradication while preserving the anal sphincter. Patients with locally advanced tumors, however, may experience complications that preclude treatment before stoma creation. Objective To evaluate the reversal rate of pretreatment stomas and the risk factors associated with nonreversal. Methods This single-institution retrospective cohort study using a prospective database included patients diagnosed with anal SCC from January 2008 to December 2020 who required a stoma before curative CRT. Results In total, 651 patients were identified; 65 required a stoma before chemoradiation due to obstruction (43.1%), rectovaginal fistula (20%), and perianal sepsis (36.9%). The stoma was reversed in nine patients after a mean follow-up of 35.8 months. Risk factors associated with a permanent stoma were perianal sepsis (p = 0.010), interruptions during radiotherapy for more than 7 days (p = 0.010), male sex (p = 0.013), poor performance status (Eastern Cooperative Oncology Group [ECOG] >= 2) (p = 0.023), large tumors (p = 0.045), and cisplatin-based chemotherapy (p = 0.047). Conclusions Pretreatment stomas are unlikely to be reversed, and risk factors for a permanent stoma are perianal sepsis, interruptions during radiotherapy for more than 7 days, male sex, poor performance status (ECOG >= 2), large tumors, and cisplatin-based chemotherapy.

- Anoplastia com plicoma sentinela para o tratamento de fissura anal crônica.(2019) SOBRADO JÚNIOR, Carlos Walter; HORA, José Américo Bacchi; SOBRADO, Lucas Faraco; GUZELA, Vivian Regina; NAHAS, Sérgio Carlos; CECCONELLO, IvanABSTRACT Objective: to evaluate the long-term results of the correction of chronic anal fissures (CAF) in patients without anal hypertonia using the technique of anoplasty with skin tag flap. Methods: we conducted a prospective study of CAF patients refractory to conservative treatment without anal hypertonia, subjected to anoplasty with the use of anal plicoma to cover the bloody area. We confirmed the absence of anal hypertonia through rectal exam and electromanometry. We applied a visual pain questionnaire and the Cleveland Clinic fecal incontinence score before and after surgery. Results: we followed 15 patients with chronic anal fissure for a mean period of 29 months (12-56). The mean age was 41 years (29-69) and the duration of symptoms ranged from six months to five years. Healing occurred between three and six weeks for 13 patients (86.7%). The other two patients underwent debridement and new anoplasty successfully. No plicoma necrosis or anal stenosis occurred in any patient. The anal incontinence score did not change after the procedure, and all patients reported reduced pain. After 12 months of follow-up, none of the patients presented recurrence or anal incontinence, and 93.3% (14/15) of the patients were very satisfied. Conclusion: fissurectomy and anoplasty with the use of sentinel plie is a safe technique that results in improvement in pain without change of fecal continence and with high satisfaction rates.
- Desarterialização transanal guiada por doppler associada ao reparo anorretal na doença hemorroidária: a técnica do THD(2012) SOBRADO-JUNIOR, Carlos Walter; HORA, José Américo BacchiINTRODUCTION: Surgical treatment for hemorrhoids should be indicated individually and is based on the predominant symptom (bleeding or prolapse), severity of disease and the presence or absence of external component (plicoma). Surgeons must choose among varied techniques the one suitable for each case. TECHNIC: The THD procedure consists of Doppler guided high ligation, selective to up six submucosal arterial branches that supply the hemorrhoids, leading to its desarterialization associated with prolapse repair (anorectal repair or lifting). It uses special equipment and kit. CONCLUSION: THD technique has shown good initial results. Because surgical technique respects the anatomy, it acts directly on the pathophysiology of the disease and corrects its principal consequences; it looks quite promising. Its initial application may be in patients with hemorrhoids grade II, which have surgical indication, grades III and IV, the latter being associated with resection of plicomas.

- Management of ulcerative colitis: a clinical update(2015) TEIXEIRA, Fabio Vieira; HOSNE, Rogerio Saad; SOBRADO, Carlos WalterThe objective of this study was to evaluate the consensus of expert societies and published guidelines on the management of ulcerative colitis, and to compare with the experience of the authors, in order to standardize procedures that would help the reasoning and decision- making process of the physician. A search was performed in scientific literature, specifically in electronic databases: Medline/Pubmed, SciELO, EMBASE and Cochrane, and the following descriptors were used: ulcerative colitis, acute colitis, clinical treatment, surgery and ran- domized trial. It can be concluded that the goals of therapy in ulcerative colitis are clinical and endoscopic remission, deep, sustained remission without corticosteroids, prevention of hospitalizations and surgeries, and improved quality of life. The surgical indications are reserved for selected cases, ranging from medical intractability, complications (severe refractory acute colitis, toxic megacolon, perforation and hemorrhage) and malignancy. Information in this review article must be submitted to evaluation and criticism of the spe- cialist responsible for the conduct to be followed, in the face of his/her reality and the clinical status of each patient. The degree of recommendation and strength of evidence were based using the GRADE sys- tem (The Grades of Recommendation, Assessment, Development, and Evaluation) described below: 1. A: Experimental or observational studies of higher consistency. 2. B: Experimental or observational studies of lower consistency. 3. C: Case reports (non-controlled studies). 4. D: Opinion without critical evaluation, based on consensus, physiological studies or animal models.
- Diagnosis and treatment of constipation: a clinical update based on the Rome IV criteria(2018) SOBRADO, Carlos Walter; CORRêA NETO, Isaac José Felippe; PINTO, Rodrigo Ambar; SOBRADO, Lucas Faraco; NAHAS, Sergio Carlos; CECCONELLO, IvanABSTRACT The aim of this study was to evaluate the published professional association guidelines regarding the current diagnosis and treatment of functional intestinal constipation in adults and to compare those guidelines with the authors' experience to standardize actions that aid clinical reasoning and decision-making for medical professionals. A literature search was conducted in the Medline/PubMed, Scielo, EMBASE and Cochrane online databases using the following terms: chronic constipation, diagnosis, management of chronic constipation, Roma IV and surgical treatment. Conclusively, chronic intestinal constipation is a common condition in adults and occurs most frequently in the elderly and in women. Establishing a precise diagnosis of the physiopathology of functional chronic constipation is complex and requires many functional tests in refractory cases. An understanding of intestinal motility and the defecatory process is critical for the appropriate management of chronic functional intestinal constipation, with surgery reserved for cases in which pharmacologic intervention has failed. The information contained in this review article is subject to the critical evaluation of the medical specialist responsible for determining the action plan to be followed within the context of the conditions and clinical status of each individual patient.
- A New Classification for Hemorrhoidal Disease: The Creation of the ""BPRST"" Staging and Its Application in Clinical Practice(2020) SOBRADO JUNIOR, Carlos Walter; OBREGON, Carlos de Almeida; SOUSA JUNIOR, Afonso Henrique da Silva e; SOBRADO, Lucas Faraco; NAHAS, Sergio Carlos; CECCONELLO, IvanPurpose: Present an updated classification for symptomatic hemorrhoids, which not only guides the treatment of internal hemorrhoids but also the treatment of external components. In addition, this new classification includes new treatment alternatives created over the last few years. Methods: Throughout the past 7 years, the authors developed a method to classify patients with symptomatic hemorrhoids. This study, besides presenting this classification proposal, also retrospectively analyzed 149 consecutive patients treated between March 2011 and November 2013 and aimed to evaluate the association between the management adopted with Goligher classification and our proposed BPRST classification. Results: Both classifications had a statistically significant association with the adopted management strategies. However, the BPRST classification tended to have fewer management discrepancies when each stage of disease was individually analyzed. Conclusion: Although there is much disagreement about how the classification of hemorrhoidal disease should be updated, it is accepted that some kind of revision is needed. The BPRST method showed a strong association with the management that should be adopted for each stage of the disease. Further studies are needed for its validation, but the current results are encouraging.
